Allergic rhinitis and acute sinusitis can both lead to the occurrence of otitis media. There exists a passage called the eustachian tube that connects the ear and the nasopharynx, which is the back part of the nasal cavity. The mucous membranes of these areas are similar. Therefore, when inflammation occurs in the nasal cavity, it can spread through this mucosal pathway to the middle ear, resulting in otitis media. The connection between the nose and the ear indicates that inflammation in the nasal area can also affect the ear, leading to ear inflammation.

Allergic rhinitis is typically triggered by allergens, such as pollen, dust mites, and pet dander, leading to swelling of the nasal mucosa and increased secretion. This inflammation not only affects the nasal cavity but can also cause dysfunction of the eustachian tube, hindering pressure regulation in the middle ear and causing fluid accumulation in the middle ear cavity, thus forming otitis media.

Acute sinusitis is an inflammation of the sinuses, usually accompanied by nasal congestion, headaches, and facial pressure. When the infection in the sinuses spreads to the eustachian tube, it leads to swelling of the tube, affecting its ventilation and drainage functions, further triggering otitis media. This infection can be caused by viruses, bacteria, or fungi, and symptoms may vary depending on the type of infection and individual differences.

There was a captivating program that demonstrated the phenomenon of smoking through the nasal or oral cavity, with smoke emerging from the ear. Although this phenomenon amazed viewers, it is not particularly complex. It exploits the aforementioned anatomical pathways; however, it is noteworthy that participants in such performances typically have a perforated eardrum. If the eardrum is intact, smoke would not be able to pass through the nasopharynx into the middle ear and then exit through the external ear canal. Additionally, recurrent otitis media may lead to hearing loss, and if not treated promptly, it can result in more severe complications, such as eardrum perforation or the spread of ear infections. Therefore, timely medical attention, appropriate medication, and preventive measures are crucial. Effective management strategies include avoiding allergens, maintaining nasal patency, and regular ear, nose, and throat check-ups to reduce the risk of otitis media.
